Managing maintenance for an item of equipment

Abstract

A method and system for maintaining an item of equipment supports the provision of predictive maintenance in a manner which eliminates or reduces downtime of the equipment. The method includes tracking performance data on the equipment or a particular component of the equipment. At least one required maintenance activity is predicted based upon the performance data with respect to a defined performance standard. Performance of the required maintenance activity is scheduled at a defined respective time based upon the prediction.

AI Technical Summary

Benefits of technology

[0007]In accordance with the invention, a method and system for managing the maintenance of an item of equipment supports the provision of maintenance in a manner which eliminates or reduces downtime of the equipment. Configuration maintenance requirements are determined for maintaining a target configuration of an item of equipment. Predictive maintenance requirements are determined for the item of equipment based on at least one of a longevity estimate, a probability of failure, and a financial analysis. A data processing system plans for the availability of at least one of resources and a component for performing maintenance consistent with the configuration maintenance requirements and the predictive maintenance requirements.

Problems solved by technology

In the prior art, maintenance of an item of the equipment may occur only after discovery of a defect or deficiency found during an inspection of the equipment.

If the inspections are delayed or too infrequent to uncover an actual or future deficiency, a user of the equipment may experience reduced availability of the equipment.

For example, an actual or future deficiency may prevent use of the equipment or may result in a failure of the equipment during routine operation.

Further, if the maintenance schedule provided by the manufacturer does not accurately reflect the true performance or reliability of the equipment, a user of the equipment may experience unwanted downtime.

If the equipment, when properly functioning, is capable of generating revenue, the downtime of the equipment may negatively impact financial results of a business associated with the equipment.

Similarly, if the equipment is essential for manufacturing or other uses, the downtime of the equipment may negatively impact financial results of a business associated with the equipment.

Thus, standard as-built documentation on the equipment may contain erroneous information on the configuration of the equipment.

Maintenance, overhaul and repair personnel may keep few records of the actual configuration of the equipment because of over-reliance on the manufacturer's specifications, manuals, and as-built documentation.

Even if configuration records are available, the records may be difficult to use or access.
